The Selfsat LDU1 is a Single LNB designed for the Selfsat H21D and H21D2 flat satellite antennas. It provides a practical solution when the antenna’s existing LNB needs to be replaced or when the system is required to serve one satellite receiver.
The LNB has one output, allowing one satellite receiver or tuner to be connected directly to the antenna. Its model-specific construction is designed for the Selfsat H21 series and provides a neat installation without a conventional external 40 mm LNB.
With a specified gain of up to 60 dB and a low typical noise figure, the LDU1 is intended for digital satellite television reception, including HDTV broadcasts.

🔧 Use and Connection
The LDU1 is installed on a compatible Selfsat H21 antenna and connected by coaxial cable to a satellite receiver or television with an integrated DVB-S/DVB-S2 tuner.
It has one output and is therefore intended for one independent receiver or tuner. A receiver equipped with multiple tuners may require additional independent LNB outputs for full functionality.
This is a model-specific Selfsat LNB and not a conventional Universal LNB with a 40 mm mounting neck.
